Changing

the

individual

such

as

the

balance

between

direct

sound

and

effect

is

called

“editing”.

“Parameters”

are

the

specific

inside

each

with

values

that

are

changeable

for

“editing”.

Editing

of

parameters

can

be

done

in

two

ways:

1)Find

a

program

that

sounds

closest

to

what

you

want,

and

create

your

own

by

editing

that

program.

2)Pick

any

program

in

the

user

area,

and

start

from

While

itis

probably

easier
